Showing you how you can blow away the default system settings and get Ubuntu to behave however you want, this down and dirty book will help you take total control of your Ubuntu system by optimizing its appearance, speed, usability, and security.
The default Ubuntu Dapper Drake installation includes some basic processes that check devices, tune the operating system, and perform housekeeping. Some of these processes are always running, while others start up periodically. Occasionally you might see your hard drive start up or grind away for a few minutes—what's going on? On mission critical servers, serious gaming boxes, and other real-time systems, unexpected processes can cause huge problems; administrators should know exactly what is running and when. The last thing a time-sensitive application needs is for a resource-intensive maintenance system to start at an unexpected time and cause the system to slow down.
In order to fine-tune your system, you will need to know what is currently running, which resources are available, and when processes start up. From there, you can tweak configurations: disable undesirable processes, enable necessary housekeeping, and adjust your kernel to better handle your needs. If you don't need it now, you will.
